total solar eclipse - sun's corona

This is a photo of the total solar eclipse of March 9 2016, that I took in Sulawesi, Indonesia.­ The whitish hair-like structure around the sun is called the "corona", and it is formed by the hot gas particles (plasma) ejected by the sun into space (eventually forming the "solar wind").­

I used a regular DSLR camera (Sony A65) with a 300mm telephoto.­ No filter needed since this was taken during the moment of "totality", when it is safe to look at the sun with the naked eyes.­

I took two photos with different exposure settings.­ The other photo is here.
